The above illustration shows the terminals of connector "J2" of left operator ECM (18) that are part of the auxiliary control system. Each terminal is described by type and function. Right Operator ECM
Illustration 9 g02646642
Under Right Operator Station Seat (21) Right operator ECM (22) Connector "J1" (23) Connector "J2"Right operator ECM (21) is located under the right operator seat. This ECM has two 70 pin connectors, connector "J1" (22) connector "J2" (23). Right operator ECM (21) monitors input devices which are located in the right operator station. This ECM communicates with the other ECMs through the Cat Data Link.

Screed Platform (24) Screed ECM (25) Connector "J1" (26) Connector "J2"Screed ECM (24) on the AS2302C Screed is located above the operator walkway on the right side of the screed. This ECM has two 70 pin connectors, connector "J1" (25) and connector "J2" (26) .Screed ECM (24) works with the operator ECMs and the machine ECM to control the auxiliary system. The screed ECM receives input signals from components on the screed. The machine electronic control system prompts the screed ECM to generate output signals to control the screed width.

Right Side of Engine (30) CAN resistorThe electronic control system is equipped with two CAN resistors. One CAN resistor (30) is mounted to the right side of the engine block near the engine ECM. The top deck plate of the operator station provides access to this component.In order to prevent data loss in the communication lines, a termination resistor is required at
